High-quality farm-to-market roads are very important to the agricultural interests in the state of Iowa, and Sioux County’s Garfield Avenue was no exception.
To address this need, Cedar Valley Corp. paved five miles of road with eight-inch concrete pavement. The project involved the regrading and paving of an existing gravel county road. A considerable amount of shoulder-grading was also performed to correct the existing foreslopes and bring them up to the current standards. The 22-foot wide paving was a variable depth design of nine inches on the outside edge and eight inches at centerline. This design method is used in Iowa to counteract the outside point loads applied by farmers’ grain wagons.
In spite of the challenges, this project was finished in only 53 working days.
The project was honored as a gold winner in the county road division of the American Concrete Pavement Association's 21st annual “Excellence in Concrete Pavement” awards, which recognize quality concrete pavements constructed in the United States and Canada.
